Meticulously researched and superbly crafted‎,‎ the ‎'‎76 Vintage Dyna Comp features the same circuitry used in the original 1976 Dyna Comp‎,‎ identical in its component layout‎,‎ silkscreen and handmade wire harness‎.‎ The key component is the CA3080 ‎"‎metal can‎"‎ integrated circuit ‎(‎IC‎)‎‎,‎ which yields quieter operation‎,‎ greater transparency and increased dynamic range‎.‎ These ICs have been out of production since the ‎'‎80s‎,‎ but MXR has tracked down a stash of them—enough to produce a limited run of these little red boxes of compression bliss‎.‎ The ‎'‎76 Vintage Dyna Comp ‎"‎tightens up‎"‎ a guitar signal‎,‎ raising the volume of quiet notes and leveling off peaks to create rich‎,‎ full bodied sustain‎.‎
